ABSTRACT:
An elbow type of fluid fitting and method for chucking for machining same wherein the fitting includes a body having a pair of fitting branches extending outwardly thereof angularly of each other. The body also includes a gripping boss extending a short distance outward thereof oppositely from one of the branches and substantially coaxial therewith. This boss facilitates chucking of a fitting blank at three separate spaced apart locations for subsequent machining and processing into the finished fitting. One of these locations is at the one branch adjacent the body and the other location is at the gripping boss to provide an increase in stability of the fitting blank during machining.
